AC Vector Drives

Description: A complex electronic device used for controlling the speed and torque of an AC motor. The vector drive can run the motor with constant torque over the whole range of speeds (although normally the torque is directly proportional to speed, vector drives offer full torque even at very low speeds). The AC motor must be rated for vector drive use (strengthened insulation to withstand voltage spikes used to run the motor during the most demanding working regimes).
